    hibernate problem

    columod Newbie

      apologies if this question is too specific for this mailing list, not sure

      i configured jboss to use hibernate as the o/r mapping layer and it seems to be working fine.
      i then created a session bean which i'm calling from a client which will persist a java object to the database (mysql) using hibernate.
      however when i make the call i get the following exception :

      i'm using the session bean provided with the hibernate 'hibtest' example code but can't seem to get past this point.
      any ideas/help greatly appreciated.
      colum.
